I don't know much about e-bikes but the "World's lightest" caught my attention. 13.6 kg - not bad esp if that includes the battery!

Seems to be another useless piece of junk. Too underpowered probably to do anything other than make up for the fact that it is a singlespeed. It is easy to make a light ebike, just put such a small battery and motor that only an ant could get any use out of it.

Brompton can be converted to an electric bike adding just 3.2 kg (7 pounds) including battery. So add that the Brompton weight you have and you end up with something between 13 and 15 kgs I think. Titanium S bar handle no mudguards single speed would be around 12 kgs I think.

Hi, my friend:

I have a Journey 7-speed Day 6 Bicycle (picture here: https://day6bicycles.com/journey.html). Mine is black it has the rear rack. I simply love it. Problem is it is a heavy bike because of the large seat and backrest and the extra long length for a semi-recumbent. I get around well enough on it, but for those little inclines and tiny uphill moments, I would love to turn on a burst of electric power assist. I don't think my needs would require more than 10-15 minutes of power for more than 2 miles.

What lightweight upgrade system could I add that would not add too much weight or take too much trouble?

Mind you I'm a beginner on all of this. I do not know much. I got a quote from a local Moped type store for $400 for adding on somekind of lead acid electric battery setup that would require changing out the front tire, and putting on that heavy battery adding on an additional total 40 pounds I think.

I need full details, links, etc. I'm in Los Angeles area, California, btw.

Thanks,

John
